This lab exercise will provide a review of laboratory techniques for measuring the mass and volume of substance the proper use of significant figures, metric units and the use of labels in all calculations. Laboratory when approximate measurements will be adequate and other times when precise measurements must be madeyou will have to make the appropriate choice there are two kinds of measurements: quantitative measurements and qualitative measurements. Experiment measurement: length, mass, volume, density, and time volume: the basic unit of volume used in the science lab is the liter (l), which is slightly larger than a quart. Pycnometry is a technique that uses the density relationship between volume and mass, and the vessel used is called a pycnometer to perform pycnometry measurements, the mass of the cylinder and the mass of a flask filled with water to a mark (a, fig 3) are recorded.
